gene-about-usGene Sisco, M Arch, MBA
Founding Partner, Development by Design, Inc.

Gene Sisco has 40 years of experience in large scale retail, urban mixed use and multifamily real estate development.  He is a developer, construction manager and award-winning architect: 45 million sf.

After practicing architecture and construction management, Mr. Sisco founded Development by Design, Inc. to fill a business management weakness in the real estate development process wherein design/architectural “intent” did not result in on time/on budget performance.

He assembled a multidisciplinary team to manage owner real estate development risk from a project’s inception through fruition.  Designing to a target budget, value engineering, and requiring periodic scope-to-cost checks are leadership benchmarks DbyD has prioritized for its “Design/Build Team.”

Domestic projects include Large Retail Regional Shopping Centers, Urban Mixed Use, Municipal, Institutional, Multifamily Residential and Entertainment. 

Abroad, DbyD has provided concepts for vertical malls, mixed use urban infill, and entertainment for developments in China, South Korea, Japan, Spain, and Italy.

In addition to actively leading development projects, Mr. Sisco has been a frequent advisor to institutional owners, providing creative project development concepts that bring together the worlds of leasing and design/build for value-added solutions. He has served as an expert witness in retail development litigation disputes.

M.B.A. from the Kellogg School of Management at Northwestern University, Master of Architecture from Harvard University’s School of Design. B.A. from Holy Cross College.

Mr. Sisco is a Global and Commercial Retail Council Member of the Urban Land Institute (ULI) and a Member of the International Council of Shopping Centers (ICSC).
